Twenty years after its discovery at the Tevatron collider at Fermilab, interest in studying the top quark at the LHC is higher than ever.
ATLAS has recently measured the total cross-sections of single top-quark and top-antiquark production via the t-channel exchange of virtual W bosons.
Precise measurements of final states containing multiple electroweak bosons (W, Z or γ) offer a powerful probe of the gauge structure of the Standard Model.
The search for new physics in 13 TeV proton collisions continues in earnest, with six new results presented at LHCP.
Understanding production cross-sections and their evolution as a function of √s are important components to understanding the measurements performed by ATLAS.
The energies of particles can be measured with the CMS electromagnetic and hadronic calorimeters without a magnet.
The two most accurate determinations of the angle, carried out at LEP and SLD, are some three standard deviations different.
The combined signal yield relative to the Standard Model expectation is measured to be 1.09±0.11.
The measured cross-sections are also used to place the most stringent limits to date on models of new physics employing any of four different dimension-six operators.
